The reactions of WF₆ with pyridine, 4-methylpyridine, 4-(dimethylamino)pyridine, and 4,4′-bipyridine (4,4′-bipy) in CH₂Cl₂ afford the Lewis-acid-base adducts WF₆(4-NC₅H₄R) (R = H, CH₃, N(CH₃)₂) and F₆W(4,4′-bipy)WF₆ as solids in quantitative yields. These adducts have been characterised in the solid state by Raman spectroscopy at ambient temperature and, in the cases of the mononuclear adducts, by X-ray crystallography at −173 °C. Furthermore, density-functional-theory (DFT-B3LYP) studies have been conducted to aid in predicting the structure of F₆W(4,4′-bipy)WF₆, assigning the vibrational frequencies of the adducts, and comparing their electronic properties.

WF ₆与吡啶，4-甲基吡啶，4-（二甲基氨基）吡啶和4,4'-联吡啶（4,4'-联吡啶）在CH ₂ Cl _{2中的反应}得到路易斯酸碱加合物WF ₆（定量收率为固体形式的4-NC ₅ H ₄ R）（R = H，CH ₃，N（CH ₃）₂）和F ₆ W（4,4'-bipy）WF ₆为固体。这些加合物在室温下通过拉曼光谱表征为固态，对于单核加合物，在-173°C下通过X射线晶体学表征。此外，已经进行了密度泛函理论（DFT-B3LYP）研究，以帮助预测F的结构。₆ W（4,4'-bipy）WF ₆，分配加合物的振动频率，并比较它们的电子性质。
